Short answer: the Kali Audio LP-6 V2. It ranks #37 of 119 powered bookshelf speakers by sound quality, rated 4.4/5, at $498; the Cambridge Audio L/R X ranks #76, rated 4.1/5, and costs $2,399, so there is little reason to consider the other one.
The Kali Audio LP-6 V2 is the better-sounding choice. Affordable studio monitors with balanced sound and solid bass, plus switches to tune them for your room. Watch for: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness.
What the Cambridge Audio L/R X does well: Active speakers with HDMI eARC, a phono input, Wi-Fi streaming, wide even dispersion, and solid bass. The catch: On-axis response is less linear than the L/R S, with dips in the bass, a peak around 1-2kHz, and a dip spanning the upper mid-range into the lower treble; Cambridge confirmed the dip is a deliberate DSP notch for a tweeter breakup resonance rather than a driver flaw, but it was audible as a mild suck-out in an AB pink-noise comparison.
Buy the Kali Audio LP-6 V2. It is rated higher for sound quality than the Cambridge Audio L/R X and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
